Description

Technical Field

[0001] This utility model relates to the field of centrifuge equipment technology, specifically an automatic balancing centrifuge with a robotic arm. Background Technology

[0002] Centrifuges, as key mechanical equipment widely used in many fields such as chemical, food, medicine, and scientific research, work on the principle of separating components of different densities, particle sizes, or shapes in a mixture using a centrifugal force field. During high-speed rotation, the components in the mixture are subjected to centrifugal forces of varying magnitudes, thereby achieving stratification or separation to meet the process requirements of different industries for material purification, concentration, and separation.

[0003] To ensure the safe and stable operation of a centrifuge, pre-use balancing is essential. Currently, manual balancing remains the most common method, requiring operators to manually adjust the sample's position on the rotor or add balancing tubes based on parameters such as sample weight and volume. However, this traditional manual balancing method has several drawbacks. On the one hand, due to the subjectivity and unavoidable operational errors of human operation, precise balancing is difficult to achieve, potentially leading to abnormal vibrations and noise during centrifuge operation. This not only accelerates the wear and tear of equipment components and shortens the equipment's lifespan but may also cause equipment malfunctions or even safety accidents. On the other hand, when processing a large number of samples to be centrifuged, each balancing operation requires finding suitable inoculum or preparing a new balancing mixture, which is cumbersome and time-consuming, significantly reducing work efficiency and failing to meet the demands of modern scientific research and production for efficient and precise separation. Utility Model Content

[0004] The purpose of this invention is to provide an automatic balancing centrifuge with a robotic arm.

[0025] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1:

[0027] Please see Figures 1-6 The illustration shows an automatic balancing centrifuge with robotic arms, including a base plate 1. A centrifuge body 2 is mounted on the base plate 1. Robotic arms 3 are symmetrically arranged on one side of the centrifuge body 2. The robotic arms 3 can automatically insert and remove centrifuge tubes, offering greater stability and safety compared to manual operation. For example, when handling liquid samples requiring stratification, this device is less likely to damage the stratification due to human handling or shaking. A back plate 4 is mounted on one side of one of the robotic arms 3. The centrifuge also includes a storage box 7 mounted on the base plate 1, containing an automatic weighing scale 8. The automatic weighing scale 8 can automatically identify the liquid weight, employing high-precision sensors and image recognition technology to acquire real-time information on centrifuged samples and inoculated materials 9. The system collects weight and volume data and synchronizes the information to the control panel 10. It automatically identifies that inoculation items 9 are installed on one side of the weighing scale 8, and that these items come in different capacities. The control panel 10 is installed on the back plate 4. Through image recognition and weighing functions, the items to be centrifuged can be placed directly in the recognition area. The robotic arm 3 can weigh and balance the sample. It can recognize voice commands and automatically convert them into working procedures, such as recognizing voice commands and setting the balancing error range and centrifugation parameters. It can set the corresponding type of inoculation item 9 according to different types of centrifuge tubes. The internal liquid weight can be increased or decreased by the equipment to achieve a balancing effect. Additionally, a balancing component 6 is installed on the base plate 1, which automatically balances the centrifuge body 2; and a moving component 5 is installed on the back plate 4, which assists the balancing component 6.

[0028] Furthermore, the moving part 5 includes a first motor 11 mounted on the back plate 4. The back plate 4 has a mounting groove 32. The output end of the first motor 11 is fixedly connected to a lead screw 12 through the mounting groove 32 via a coupling. A slider 13 is threadedly connected to the outside of the lead screw 12. The end of the lead screw 12 away from the first motor 11 is rotatably connected to the inner wall of the mounting groove 32. The slider 13 is slidably connected to the mounting groove 32. By sliding the slider 13 with the mounting groove 32, the slider 13 can be limited and guided, thereby facilitating the horizontal movement of the slider 13.

[0029] Specifically: A connecting plate 14 is fixedly connected to the outside of the slider 13 through the mounting groove 32. The connecting plate 14 is made of aluminum alloy, which is lightweight and durable. Vertical plates 16 are symmetrically installed below the connecting plate 14. A second motor 15 is installed on the outside of one of the vertical plates 16. Both the first motor 11 and the second motor 15 provide power to the moving part 5. A screw 17 is fixedly connected to the second motor 15 through one of the vertical plates 16. A moving block 18 is threadedly connected to the outside of the screw 17. A limit rod 19 is installed between the two vertical plates 16. The limit rod 19 is polished and has a smooth surface to facilitate the movement of the moving block 18. The moving block 18 is slidably connected to the limit rod 19. A mounting plate 20 is installed at the bottom of the moving block 18. Electric push rods 21 are symmetrically installed below the mounting plate 20. Push plates 22 are installed at the bottom of both electric push rods 21. The electric push rods 21 drive the push plates 22 to move, thereby facilitating the balancing part 6 to add or remove liquid inside the seed item 9.

[0030] Example 2:

[0031] This embodiment provides a further explanation of Example 1, based on... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it is worth noting that a water tank 23 is provided on the base plate 1. The water tank 23 is made of stainless steel. A water pump 24 is installed above the water tank 23. The input end of the water pump 24 is fixedly connected to an input pipe 25. The input pipe 25 is a T-shaped pipe. A water suction pipe 26 is installed outside the input pipe 25. The other end of the water suction pipe 26 is fixedly connected to and communicates with the water tank 23. Water is pumped from the water tank 23 through the water suction pipe 26, which facilitates the liquid addition operation of the breeding item 9.

[0032] Specifically, a water suction hose 27 is fixedly connected to the outside of the input pipe 25. The end of the water suction hose 27 away from the input pipe 25 is fixedly connected to one of the push plates 22. When it is necessary to perform a liquid reduction operation on the inoculation item 9, the liquid inside the inoculation item 9 can be extracted through the water suction hose 27.

[0033] At the same time, refer to Figure 5 and Figure 6 As shown, an output pipe 28 is fixedly connected to the output end of the water tank 23. A drain pipe 29 is fixedly connected to the outside of the output pipe 28. The drain pipe 29 passes through and extends into the inside of the water tank 23. A water inlet pipe 30 is fixedly connected to the outside of the output pipe 28. The water inlet pipe 30 is fixedly connected to another push plate 22. Valves 31 are installed on the outside of the output pipe 28, the drain pipe 29, the input pipe 25, and the pumping pipe 26. The pumping direction of the water pump 24 can be controlled by the valve 31, which facilitates the automatic addition or reduction of liquid in the seed material 9, thereby facilitating automatic balancing and improving balancing efficiency and accuracy.

[0034] The principle behind this solution is as follows:

[0035] First, the first motor 11 drives the lead screw 12 to rotate, which drives the slider 13 to move horizontally in the mounting groove 32. With the help of the connecting plate 14, the vertical plate 16 and the screw 17-limiting rod 19 driven by the second motor 15, the moving block 18 can be flexibly positioned in the two-dimensional plane, ensuring that the electric push rod 21 and push plate 22 under the mounting plate 20 can accurately reach the target position.

[0036] Secondly, when the control panel 10 determines that the weight of the breeding item 9 needs to be increased, the external valve 31 of the water pump 26 is activated. The water pump 24 draws water from the water tank 23 through the water pump 26, and delivers it to the target breeding item 9 through the output pipe 28 and the water filling pipe 30. Conversely, if weight reduction is required, the external valve 31 of the water pump 26 is closed, and the external valve 31 of the water suction hose 27 is activated. The water suction hose 27 then draws liquid, which flows back to the water tank 23 through the drain pipe 29. The water circuit control system composed of valves 31 can accurately switch the liquid flow direction according to the balancing requirements. In conjunction with the electric push rod 21 to control the extension and retraction of the push plate 22, it can achieve precise increase or decrease of trace amounts of liquid, ensuring that the balancing error is controlled within a very small range.

[0037] Finally, robotic arm 3 automatically inserts and removes centrifuge tubes, facilitating precise operation.

[0038] It should be noted that the robotic arm 3, control panel 10, first motor 11, second motor 15, electric push rod 21 and water pump 23 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
